KOA1 electronic track circuits
General description
- double rail track circuits limited by insulated joints
- used for electrified tracks and for tracks with independent traction with electrically heated passenger coaches
- minimum maintenance needs
- centralized equipment
- detection of electrical integrity of rail tracks
- formed by three HW parallel branches
Basic technical description
- complies with CENELEC standards
- the system enables simple modification of present KO by replacing up to 8 track relays with 1 set of TCR
- a part of the system are TCR track receivers detecting track voltage and digitally assessing it
- checks of isolated joints is done by electronically detecting the phase shift
- the KOA1 enables the operation of tractive vehicles with higher threatening currents in areas of signal frequencies
- transmission of codes of the continuous train control
